Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513242, here are decompositions:

3 + 513239 = 513242
73 + 513169 = 513242
139 + 513103 = 513242
211 + 513031 = 513242
229 + 513013 = 513242
241 + 513001 = 513242
283 + 512959 = 513242
313 + 512929 = 513242

Showing the first eight; more decompositions exist.
